it's a decent app for daily brain training. but it's too bad that you have to subscribe for premium, and that you can't pay a one time fee. the cost of yearly subscription has been reduced from 80 USD to 40 USD, but it's still a subscription which I find unacceptable. I would have paid to own the game. But if subscribing is the only way to get premium, I will be looking for another game. I refuse to give honest feedback about how to improve the game until it is possible to own it.

Some exercises have the time running even when the question changes. Makes you lose a second every time in certain games like Coloured Words. Also time for one line is ridiculously low. Could have 10 more seconds there since drawing lines takes a little time and feedback is bad so lines abruptly end in the middle while drawing, this you have to redraw again. Otherwise the game is fun and challenging. Would definitely have better rating with the time running issues fixed.

The game is awesome in every way, really helpful, however, I'm seriously disappointed, I just opened the app and noticed my progress is gone, I'm constantly dropping levels, even though I complete the requirements, and I have the pro, you guys should fix this, otherwise, I'll seriously think about cancelling my subscription and no longer use the app
